Plenty of room for transformers plugged into a 4g splitter and the sturdy plastic construction and decent seals have kept it bone dry over the last 5 weeks. Top product, bargain.

## Questions & Answers

**Q: Size on website is wrong can you confirm size?**
A: Interior dimensions are: 32.5cm x 21cm x 8cm.

**Q: Do you put a normal indoor extension lead inside and then plug outdoor lights in. How many plugs does it take?**
A: The socket end of your extension lead fits inside the box and it would accommodate up to 4 sockets providing your plugs are standard 3pin and not RCD type.

**Q: I need something safe and waterproof to charge mobility scooter overnight outside? Is this ok for that?**
A: Very good I bought 4 of them for outside christmas lights ans have already used them for lights at a birthday

**Q: Can i use a normal indoor extention lead and use the box to use it outside or do i need an outdoor exatention lead too?**
A: Well, the box is certainly a weatherproof enclosure so long as you feed the flex cable through the rubber holes and make sure that the clamp is firmly in place afterwards.  Therefore an indoor extension lead would be OK and you can rest the socket part within the box.  The plug socket in the house must be RCD protected.  I would recommend mounting/fixing the box on something solid outdoors.  Also you will need to protect the outdoor section of the flex cable from damage.

### ⭐⭐⭐⭐⭐ Weatherproof box
*by B***N on 16 May 2026*

Good quality box ideal for keeping temporary outdoor sockets dry for Christmas tree lights etc.

### ⭐⭐⭐⭐ Simple, good prodcut, does what it sets out to do
*by I***N on 3 September 2025*

The only real tricky part relating to this is mounting it, however this is very much a reflection on the person fitting it than the prodcut itself. The box is of a good size and accomdates the dual socket extension which I was using. It also has a good depth, which is really useful given the height increase in plugs used for garden lighting etc. The product seals well, I have checekd it on numerous occasions after rain (including heavy rain) and the inside has been completely dry. It is a simple product, done well.
